Desarrollo de una metodología para el monitoreo ambiental de cursos hídricos urbanos intervenidos con obras hidráulico sanitarias por la EPMAPS. Caso de estudio: quebrada ortega y aportantes

Abstract

The current study focuses on the development of a methodology to perform environmental monitoring of the urban hydraulic resources intervened with sanitary civil works by the Metropolitan Public Company of Water Treatment and Sanitation on the Ortega ravine and its tributaries. The rainy and dry seasons where defined based on hydraulic and hydrologic studies performed on the ravine. In order to characterize the physiochemical and microbiological parameters, multiple factors were taken into account such as the current Ecuadorian environmental legislation (Ministerial agreement No 097-A, Annex 1 from book VI, tables 2 and 2-a, Official Record 387, June 4, 2015), and the historic records of the ravine of 2012, 2013, and 2014. Moreover, the study of aquatic macroinvertebrates was carried out through the BMWP index to characterize the water quality running through the Ortega ravine and its tributaries. Thus, a methodology, as a technical base to control the anthropogenic pollution of rivers, is proposed as part of the plan of decontamination of Quito Rivers.
